Question

exam 2: periodicity & electron configuration/em spectrum
which color of light has more energy than green?
frequency in hz
visible light
wavelength in nm
blue
red
yellow
orange

Explanation:

Step1: Recall energy - frequency relation

The energy of a photon is given by $E = h
u$, where $h$ is Planck's constant and $
u$ is the frequency. Higher frequency means higher energy.

Step2: Analyze visible - light spectrum

In the visible - light spectrum, the order of increasing frequency (and thus increasing energy) is red < orange < yellow < green < blue < violet.

Answer:

A. blue
